Answer: Now it is proved that the atom consists of particles like electrons, protons, and neutrons.
Explanation: because he did not have the tech we do to understand atoms
Explanation:
The pKa value of acetic acid is determined experimentally by plotting pH titration curve.
The hydrogen ion, H+ concentration can be determined by performing a pH titration of a weak acid with a strong base like NaOH etc.
Starting from the dissociation equation for the acid,
HA(aq) + OH-(aq) --> H3O+(aq) + A−(aq)
we obtain for the point of half equivalence (where half of the acid has reacted with the base):
[A−] = [HA].
From the equilibrium equation
it therefore follows that
pKa = pH.
Explanation:
First of all , there were a total charge of +13e (6 protons from carbon and 7 protons from nitrogen), that meant there requires to be a total charge of +13e after the collision occurred. Listed is 16 protons (+16e), 3 antiprotons (-3e), 8 positrons (+8e) and 16 neutral particles (0e), so the total charge listed is +21e, meaning an excess of +8e, meaning you need 8 electrons (-8e) to balance out the charge.
